ANTISKIDDING DEVICE.

Specification of Letters Patent.

Application filed May 11, 1910.

Patented Aug. 23, 1910.

Serial No. 560,702.

To all whom it may concern:

Be it known that 1, WILLIAM REAGAN, citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inAntiskidding Devices; and I do hereby declare the followingto be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention relates to anti-skidding de-" vices for vehicle-wheels,but more particularly for that class of wheels which are provided withpneumatic or cushion tires; and it consists of roups of closely-relatedguard-members an calk-bearin members arranged, at intervals, around t ecircumference of the wheel.

One of the chief objects of the invention is to provide against abradingor cutting the tires. I

Another object is to prevent the calks from penetrating the surface ofthe roadbed to such an extent as will tear up, or disfigure the same incase the surface is composed of asphaltum or concrete.

Other ob ects of the invention will become apparent upon a more completedisclosure thereof.

In the drawings :--Figure 1 is a side elevation of an automobile wheel,showing my anti-skidding device applied thereto; Fig.

2, a transverse or cross-section of the tire,

showing a group of the anti-skidding members arranged thereon; Fi 3, anouter face view of a similar group; *ig.,4=, a perspective View of oneof the guard-members and one of the calk-bearing sections pivoted together; Fig. 5, a vertical section of the interlocking device forsecurin the respective ends of the retaining-mem ers to ether; Fig. 6, aside elevation of a group 0 modified guard-members,'and calk-bearinmembers, and Fi 7 a perspective view 0 one of the modifie thereto. Inthe several views,'the numeral 1 ind cates a number of guard-members,preferably composed of two plates 2, 2, spaced apart and connectedtogether at their back or under sides, as shown in Fig. 5; 'The backs ofthe guard-members are made slightly rounding, especially their sideguard-members, with detach-' able back, showing a separate back appliededges, so as to provide against all danger of abrading or cutting thetire, and to allow for a slight rolling motion on the tire. Pivotedbetween the guard-plates, attheir adjacent ends, are calk-bearingmembers 3, composed preferably of a plurality of plates provided withsharpened calks4 for engaging the surface of the road-bed. The points ofthe calks are substantially in the same horizontal plane as the topedges of the guard-plates forming the guard-members, and being thusprotected the calksare prevented from entering the surface of theroadway to an extent suflicient to tear up or injure such surface, thetop edges of said guard-plates serving not only to limit the penetratingaction of the calks, but to check the tendency to skid.

Pivoted to the end guard-member of each group of anti-skidding devices,is a securingblock 5 having oppositely-disposed hooks 6 which receivethe slotted ends of links 7. The hooks of the securing-blocks are soconstructed and arranged that, because of their pivotal relation withthe said uard-members, disengagement of the links is prevented, butwithdrawal of the pintle will allow of the removal of the links from thehooks,-

The respective ends of the retainingmembers are securely fastenedtogether by an inter-locking device pivoted to, one of the end links'ofsaid retaining-member, as shown at 8, Figs. 1 andfi. The interlockingdevice consists referably of a suitable case 9, in one end of which ispivoted a lockinglever 10, having a hook-shape end 11 in which theslotted end of the other end link of the retaining-member is received,the case being provided with slotted-opening 12, through which the endof the link is passed, when slipped over the locking-lever, into itsseat in the hook-shape end. The ivotal point of the locking-lever is sovlocate with relation to the seat in the hook-shape end, that when" thelever is pushed or forced into locking position, the strain exerted bythe retaining-member will firmly hold said lever against any accidentaldisengagement of the Instead of employing the gripping devices shown inmodified formshown in Figs. 6 and 7, in which the calk-bearing membersare ivoted to guard-members not rovided wit back portions, being composeof-guard-plates 13,

Figs. 1 to 5 inclusive, I make the said guards, theends of t e calksbeing in 13, which have their back edges slightly curved, to conform tothe lateral curvature of the tire, and their corners rounded, as havealso the calk-bearin members 14, so that the tendency to abra e or cutthe tire is reduced to a minimum. This form of the device is especiallyadapted for use on cushion-tired wheels.

It will be noted that, while I have'shown the calk bearing memberscomposed of two plates or sections, they ma be formed from a singleplate of require width. It will also be noted that these members are ofless width than the guard-members, and in consequence thereof thetendency of the calks, which are thus protected by said guardmembers, totear up or mar the surface of the roadway, is further diminished,without affecting the gripping qualities of said calkbearing sections,which, in practice, are

shown to be highly efficient in preventing skidding, but if desired aback 15, ha ing bent-up sides 16 may be employed, so as to secure theresults obtained by the guardmembers 1, heretofore described.

- Having thus fully described my invention, what I claim, is

1. An anti-skidding device for flexibly-- tired wheels, including incombination calkbearing members, guard-members for limiting thepenetration of the calks, said calkbearing-members being pivoted betweensaid guards, and detachab -connected securingblocks at each end of thepivoted members.

2. An anti-skidding device for flexibl tired wheels, including incombination calkbearing-members, guard-members for limiting thepenetration of the calks, said calk bearing-members being pivotedbetween said guards, and devices for retaining the pivoted members andguards onto the wheel.

3. An anti-skidding device for flexiblytired wheels, including incombination calkbearing-members and guard-members, saidcalk-bearing-members bein "pivoted between scenic substantially the sameplane as the top edges of the guards.

4. An anti-skidding device for flexiblytired wheels, including incombination calkbearing-members, guard-members, said calkbearing-membersbeing pivoted between said guards, the ends of the calks being insubstantially the same plane as the top edges of the guards, andretaining-links for holding the pivoted members onto the Wheel.

5. An anti-skidding device for flexiblytired wheels, having incombination calkbearing members and guard members pivoted together, theends of the calks being in substantially the same plane as the top edgesof the guard-members, retainingmembers composed of a plurality of linksto which the pivoted members are connected, and interlocking means forfastening the links together. p

6. An anti-skidding device for flexiblliytired wheels, having incombination ca bearin members and guard members pivote together, theends of the calks being in substantially the same plane as the to edgesof the guard-members, said guar members being united by a back, slightlyrounded, whereby abrasion and cutting of the tire is prevented.

7. An anti-skidding device for flexiblytired wheels, comprisingcalk-bearing-memhers and guard-members pivoted together, said ivotedmembers being-grouped at intervals around the wheel, the ends of thecalks being in substantially the same plane as the top edges of theguard-members, securing-blocks pivoted to each end of each group,retaining-links for holding the pivoted members onto the wheel, andmeans for locking the end links together.

In testimony whereof I aiiix my signature, in the presence of twowitnesses,

WILLIAM REAGAN.
